Meteorological Observations for Novernber 1829. 79 



ing the first time this autumn. There was a difference of 17 degrees be- 

 tween the maximum temperature of the 12th and 25th, and a difference of 

 22 degrees between the minimum temperature of the 12th and 16th ! 



A great depression of the mercury in the barometer took place on the 

 21st and 22nd, with a fresh wind from the S.E., succeeded by a S.W. wind. 

 On the 23rd a very heavy tjale set in from the N.E., and occasioned much 

 damage among the ships and vessels in the Downs, and along the eastern 

 shore of the British Channel on the 24th : it brought on snow here, which 

 continued to fall throughout the night and most of the following day, when 

 there was no variation of temperature at the ground from the freezing 

 point, and the depth was three inches. This was unusually early for the 

 appearance of snow in the immediate vicinity of the sea, as we seldom see 

 any lie on the ground here before Christmas in the coldest winters. The 

 bending aspect of the trees and shrubs, which were heavily clad with a 

 snowy garment, contrasted with the long transparent icicles that were pen- 

 dent from the roofs of the houses, had a magnificent, yet novel appearance 

 in November : a rising temjierature, with wind and rain in the night, dis- 

 solved nearly all the snow on the level ground by the morning of the 26th. 



More favourable weather for getting the seed into the ground last month 

 and the early part of this, could not have been desired ; and even that depth 

 of snow, from its containing and absorbing so much oxygen, has served as 

 the best compost to the neighbouring lands, and softened the ground sur- 

 prisingly. 



The mean temperature of the external air this month is three degrees 

 and three quarters lower than the mean of November for many years [)ast. 



The atmospheric and meteoric phenomena that have come within our 

 observations this month, are, two meteors, one rainbow, and nine gales of 

 wind, or days on which they have prevailed ; namely, two from the North, 

 three from the North-east, two from the East, one from the South-west, 

 and one from the West.
